Jeff Wall presents his images in lightboxes. Wikipedia says that they are backlit Cibachromes. http://en.wikipedia.org/wiki/Jeff_Wall ...but I believe that he is using Duratrans. His images are about 6x8 feet or so in size and reportedly sell for a million dollars apiece. Jeff is having a major retrospective at MOMA http://moma.org/exhibitions/2007/jeffwall/ Here is a video. http://vernissage.tv/blog/2007/03/05/jeff-wall-retrospective-museum-of-moder n-art-moma/ Good luck with yours.
